JAXP API using DOM Parser |
|
|
used to append the element to the DOM
document.
//create the root element
Element root = doc.createElement(“root”);
//all it to the xml tree
doc.appendChild(root); |
(2) Adding Comment Element to DOM Tree
The doc.createComment method is used to
reate Comment object.
//create a comment
Comment comment =
doc.createComment(“This is comment”);
//add in the root element
root.appendChild(comment); |
(3) Adding Child Element to DOM Tree
The doc.createElement method is used to
create Child element.
//create child element
Element childElement =
doc.createElement(“Child”);
//Add the atribute to the child
childElement.setAttribute(“attribute1”,”The
value of Attribute 1");
root.appendChild(childElement); |
(4) Printing the DOM Tree on console
An finally we will print the DOM tree on the
console with the following code:
TransformerFactory tranFactory =
TransformerFactory.newInstance();
Transformer aTransformer =
tranFactory.newTransformer();
Source src = new DOMSource(doc);
Result dest = new
StreamResult(System.out);
aTransformer.transform(src, dest); |
